The deal means a second customer will join Pakistan in operating the Saab Microwave Systems Erieye radar-equipped Saab 2000 AEW&C. Islamabad has so far received two of its four aircraft, plus one without a radar to support training activities, says Flightglobal's MiliCAS database.

The newly ordered system will involve the refurbishment of one of about 56 existing Saab 2000s. The deal also includes ground equipment and logistics and support services, the company says.

The Erieye radar has previously been ordered by Sweden, Thailand and the United Arab Emirates on the Saab 340 turboprop. The same sensor also equips modified Embraer ERJ-145s for Brazil, Greece and Mexico.
